So you get a location on mobile calls - Richard> since when? Nobody cared 10 years ago. I'm not sure I understand the point you're trying to make here. It is more than possible for a mobile phone's location to be identified. Emergency services can and do use triangulation of a phone's signal to its base stations to work out where a mobile phone is physically located. [Almost every week the mountain rescue people do this to save lost or injured hillwalkers and climbers on the Scottish mountains.] This location info is obviously much more important than any billing address for the phone's owner (if there is one). Now I suppose there's no parallels for that kind of thing with VoIP. Somebody could be using NAT or tunnelling and that would mean the SIP server has no idea where the SIP session originated from.
